Abstract
PURPOSE: The purpose of this study was to evaluate the in vitro antifungal effects of n-butyl-2-cyanoacrylate (nB2CA; Histoacryl Blue; B. Braun, Melsungen, Germany) against a variety of different fungal species.
METHODS: Inocula taken from suspensions prepared with Aspergillus flavus, Aspergillus fumigatus, Aspergillus niger, Aspergillus ochraceus, Aspergillus oryzae, Fusarium solanii, Fusarium oxysporum, Trichoderma spp., Rhizomucor spp., Scedosporium apiospermum, Penicillium commune, Phoma glomerata, and Chrysosporium spp. molds and Candida albicans, Candida glabrata, Candida parapsilosis, Candida kruzei, Candida dubliniensis, Candida tropicalis, Candida kefyr, and Trichosporon asahii yeasts were spread on the surface of RPMI1640 agar media. Then, 50 μL of nB2CA was dropped on the surface of these media and they were incubated at 35°C. Observation of a clear zone of inhibition around the nB2CA was regarded as an indicator of the susceptibility of the fungi to nB2CA, and the absence of this zone was interpreted as an indicator of nonsusceptibility. The inhibition zone diameter was measured across the largest clear zone.
RESULTS: A zone of inhibition was observed around nB2CA for all of the yeast and mold species except A. flavus, A. oryzae, and Chrysosporium spp. Among molds, the largest zone of inhibition was observed with P. glomerata (25.7 ± 0.6 mm), whereas among yeasts, the largest zone of inhibition was observed with C. kruzei (19.3 ± 1.5 mm).
CONCLUSIONS: nB2CA has shown antifungal activity against 18 different mold and yeast species, but not against A. flavus, A. oryzae, and Chrysosporium spp. molds.
